Hello all, I have a Powerbook 1.5ghz that was given to me and I want to use it to run some OS9 games. I've read that you need a special disk of OS9 to install classic on tiger.. I don't have this, but what I do have is a retail disk of OS9, the one with orange lettering. Am I out of luck, or can I use my retail disk? Sorry for my lack of knowledge on the subject, I was in 2nd grade when OS9 was still popular lol.
